Description of the Related Art

RAS represents a group of closely related monomeric globular proteins of189 amino acids (21 kDa molecular mass) which are associated with theplasma membrane and which bind either GDP or GTP. RAS acts as amolecular switch. When RAS contains bound GDP, it is in the resting oroff position and is “inactive”. In response to exposure of the cell tocertain growth promoting stimuli, RAS is induced to exchange its boundGDP for a GTP. With GTP bound, RAS is “switched on” and is able tointeract with and activate other proteins (its “downstream targets”).The RAS protein itself has a very low intrinsic ability to hydrolyze GTPback to GDP, thus turning itself into the off state. Switching RAS offrequires extrinsic proteins termed GTPase-activating proteins (GAPs)that interact with RAS and greatly accelerate the conversion of GTP toGDP. Any mutation in RAS which affects its ability to interact with GAPor to convert GTP back to GDP will result in a prolonged activation ofthe protein and consequently a prolonged signal to the cell telling itto continue to grow and divide. Because these signals result in cellgrowth and division, overactive RAS signaling may ultimately lead tocancer.

Structurally, RAS proteins contain a G domain which is responsible forthe enzymatic activity of RAS — the guanine nucleotide binding and thehydrolysis (GTPase reaction). It also contains a C-terminal extension,known as the CAAX box, which may be post-translationally modified and isresponsible for targeting the protein to the membrane. The G domain isapproximately 21-25 kDa in size and it contains a phosphate binding loop(P-loop). The P-loop represents the pocket where the nucleotides arebound in the protein, and this is the rigid part of the domain withconserved amino acid residues which are essential for nucleotide bindingand hydrolysis (Glycine 12, Threonine 26 and Lysine 16). The G domainalso contains the so called Switch I (residues 30-40) and Switch II(residues 60-76) regions, both of which are the dynamic parts of theprotein which are often represented as the “spring-loaded” mechanismbecause of their ability to switch between the resting and loaded state.The key interaction is the hydrogen bonds formed by Threonine-35 andglycine-60 with the γ-phosphate of GTP which maintain Switch 1 andSwitch 2 regions respectively in their active conformation. Afterhydrolysis of GTP and release of phosphate, these two relax into theinactive GDP conformation.

The most notable members of the RAS subfamily are HRAS, KRAS and NRAS,mainly for being implicated in many types of cancer. However, there aremany other members including DIRAS1; DIRAS2; DIRAS3; ERAS; GEM; MRAS;NKIRAS1; NKIRAS2; NRAS; RALA; RALB; RAP1A; RAP1B; RAP2A; RAP2B; RAP2C;RASD1; RASD2; RASL10A; RASL10B; RASL11A; RASL11B; RASL12; REM1; REM2;RERG; RERGL; RRAD; RRAS and RRAS2.

Mutations in any one of the three main isoforms of RAS (HRAS, NRAS, orKRAS) genes are among the most common events in human tumorigenesis.About 30% of all human tumors are found to carry some mutation in RASgenes. Remarkably, KRAS mutations are detected in 25-30% of tumors. Bycomparison, the rates of oncogenic mutation occurring in the NRAS andHRAS family members are much lower (8% and 3% respectively). The mostcommon KRAS mutations are found at residue G12 and G13 in the P-loop andat residue Q61.

G12C is a frequent mutation of KRAS gene (glycine-12 to cysteine). Thismutation had been found in about 13% of cancer occurrences, about 43% oflung cancer occurrences, and in almost 100% of MYH-associates polyposis(familial colon cancer syndrome). However targeting this gene with smallmolecules is a challenge.

Accordingly, while progress has been made in this field, there remains aneed in the art for improved compounds and methods for treatment ofcancer, for example by inhibition of KRAS, HRAS or NRAS. The presentinvention fulfills this need and provides further related advantages.

The term “agonist” as used herein refers to a compound having theability to initiate or enhance a biological function of a targetprotein, whether by inhibiting the activity or expression of the targetprotein. Accordingly, the term “agonist” is defined in the context ofthe biological role of the target polypeptide. While preferred agonistsherein specifically interact with (e.g., bind to) the target, compoundsthat initiate or enhance a biological activity of the target polypeptideby interacting with other members of the signal transduction pathway ofwhich the target polypeptide is a member are also specifically includedwithin this definition.

As used herein, “agent” or “biologically active agent” refers to abiological, pharmaceutical, or chemical compound or other moiety.Non-limiting examples include a simple or complex organic or inorganicmolecule, a peptide, a protein, an oligonucleotide, an antibody, anantibody derivative, antibody fragment, a vitamin derivative, acarbohydrate, a toxin, or a chemotherapeutic compound.

“Prodrug” is meant to indicate a compound that may be converted underphysiological conditions or by solvolysis to a biologically activecompound described herein (e.g., compound of structure (I)). Thus, theterm “prodrug” refers to a precursor of a biologically active compoundthat is pharmaceutically acceptable. In some aspects, a prodrug isinactive when administered to a subject, but is converted in vivo to anactive compound, for example, by hydrolysis. The prodrug compound oftenoffers advantages of solubility, tissue compatibility or delayed releasein a mammalian organism (see, e.g., Bundgard, H., Design of Prodrugs(1985), pp. 7-9, 21-24 (Elsevier, Amsterdam). A discussion of prodrugsis provided in Higuchi, T., et al., “Pro-drugs as Novel DeliverySystems,” A.C.S. Symposium Series, Vol. 14, and in BioreversibleCarriers in Drug Design, ed. Edward B. Roche, American PharmaceuticalAssociation and Pergamon Press, 1987, both of which are incorporated infull by reference herein. The term “prodrug” is also meant to includeany covalently bonded carriers, which release the active compound invivo when such prodrug is administered to a mammalian subject. Prodrugsof an active compound, as described herein, are typically prepared bymodifying functional groups present in the active compound in such a waythat the modifications are cleaved, either in routine manipulation or invivo, to the parent active compound. Prodrugs include compounds whereina hydroxy, amino or mercapto group is bonded to any group that, when theprodrug of the active compound is administered to a mammalian subject,cleaves to form a free hydroxy, free amino or free mercapto group,respectively. Examples of prodrugs include, but are not limited to,acetate, formate and benzoate derivatives of a hydroxy functional group,or acetamide, formamide and benzamide derivatives of an amine functionalgroup in the active compound and the like.

In some embodiments, prodrugs include compounds of structure (I) havinga phosphate, phosphoalkoxy, ester or boronic ester substituent. Withoutbeing bound by theory, it is believed that such substituents areconverted to a hydroxyl group under physiological conditions.Accordingly, embodiments include any of the compounds disclosed herein,wherein a hydroxyl group has been replaced with a phosphate,phosphoalkoxy, ester or boronic ester group, for example a phosphate orphosphoalkoxy group. For example, in some embodiments a hydroxyl groupon the R¹ moiety is replaced with a phosphate, phosphoalkoxy, ester orboronic ester group, for example a phosphate or alkoxy phosphate group.Exemplary prodrugs of certain embodiments thus include R¹ moietiessubstituted with one of the following substituents:

The term “in vivo” refers to an event that takes place in a subject’sbody.

Embodiments of the invention disclosed herein are also meant toencompass all pharmaceutically acceptable compounds of structure (I)being isotopically-labelled by having one or more atoms replaced by anatom having a different atomic mass or mass number (i.e., an “isotopicform” of a compound of structure (I)). Examples of isotopes that can beincorporated into the disclosed compounds include isotopes of hydrogen,carbon, nitrogen, oxygen, phosphorous, fluorine, chlorine, and iodine,such as ²H, ³H, ¹¹C, ¹³C, ¹⁴C, ¹³N, ¹⁵N, ¹⁵O, ¹⁷O, ¹⁸O, ³¹P, ³²P, ³⁵S,¹⁸F, ³⁶Cl, ¹²³I, and ¹²⁵I, respectively. These radiolabeled compoundscould be useful to help determine or measure the effectiveness of thecompounds, by characterizing, for example, the site or mode of action,or binding affinity to pharmacologically important site of action.Certain isotopically-labeled compounds of structure (I), for example,those incorporating a radioactive isotope, are useful in drug and/orsubstrate tissue distribution studies. The radioactive isotopes tritium,i.e. ³H, and carbon-14, i.e. ¹⁴C, are particularly useful for thispurpose in view of their ease of incorporation and ready means ofdetection.

Substitution with heavier isotopes such as deuterium, i.e., ²H, mayafford certain therapeutic advantages resulting from greater metabolicstability, for example, increased in vivo half-life or reduced dosagerequirements, and hence are preferred in some circumstances.

Substitution with positron emitting isotopes, such as ¹¹C, ¹⁸F, ¹⁵O and¹³N, can be useful in Positron Emission Topography (PET) studies forexamining substrate receptor occupancy. Isotopically-labeled compoundsof structure (I) can generally be prepared by conventional techniquesknown to those skilled in the art or by processes analogous to thosedescribed in the Examples as set out below using an appropriateisotopically-labeled reagent in place of the non-labeled reagentpreviously employed.

Certain embodiments are also meant to encompass the in vivo metabolicproducts of the disclosed compounds. Such products may result from, forexample, the oxidation, reduction, hydrolysis, amidation,esterification, and the like of the administered compound, primarily dueto enzymatic processes. Accordingly, the embodiments include compoundsproduced by a process comprising administering a compound of thisinvention to a mammal for a period of time sufficient to yield ametabolic product thereof. Such products are typically identified byadministering a radiolabeled compound of the invention in a detectabledose to an animal, such as rat, mouse, guinea pig, monkey, or to human,allowing sufficient time for metabolism to occur, and isolating itsconversion products from the urine, blood or other biological samples.

“Stable compound” and “stable structure” are meant to indicate acompound that is sufficiently robust to survive isolation to a usefuldegree of purity from a reaction mixture, and formulation into anefficacious therapeutic agent.

In some embodiments, the solvent iswater, in which case the solvate is a hydrate. Alternatively, in otherembodiments, the solvent is an organic solvent. Thus, the compounds ofthe present invention may exist as a hydrate, including a monohydrate,dihydrate, hemihydrate, sesquihydrate, trihydrate, tetrahydrate and thelike, as well as the corresponding solvated forms. In some aspects, thecompound of the invention is a true solvate, while in other cases, thecompound of the invention merely retains adventitious water or is amixture of water plus some adventitious solvent.

“Optional” or “optionally” means that the subsequently described eventof circumstances may or may not occur, and that the description includesinstances where said event or circumstance occurs and instances in whichit does not. For example, “optionally substituted aryl” means that thearyl radical may or may not be substituted and that the descriptionincludes both substituted aryl radicals and aryl radicals having nosubstitution.

A “pharmaceutical composition” refers to a formulation of a compound ofthe invention and a medium generally accepted in the art for thedelivery of the biologically active compound to mammals, e.g., humans.Such a medium includes all pharmaceutically acceptable carriers,diluents or excipients therefor.

The compounds of the invention (i.e., compounds of structure (I) andembodiments thereof), or their pharmaceutically acceptable salts maycontain one or more centers of geometric asymmetry and may thus giverise to enantiomers, diastereomers, and other stereoisomeric forms thatare defined, in terms of absolute stereochemistry, as (R)— or (S)— or,as (D)— or (L)— for amino acids. Embodiments thus include all suchpossible isomers, as well as their racemic and optically pure forms.Optically active (+) and (-), (R)— and (S)—, or (D)— and (L)— isomersmay be prepared using chiral synthons or chiral reagents, or resolvedusing conventional techniques, for example, chromatography andfractional crystallization. Conventional techniques for thepreparation/isolation of individual enantiomers include chiral synthesisfrom a suitable optically pure precursor or resolution of the racemate(or the racemate of a salt or derivative) using, for example, chiralhigh pressure liquid chromatography (HPLC). When the compounds describedherein contain olefinic double bonds or other centers of geometricasymmetry, and unless specified otherwise, it is intended that thecompounds include both E and Z geometric isomers. Likewise, alltautomeric forms are also intended to be included.

Embodiments of the present invention include all manner of rotamers andconformationally restricted states of a compound of the invention.Atropisomers, which are stereoisomers arising because of hinderedrotation about a single bond, where energy differences due to stericstrain or other contributors create a barrier to rotation that is highenough to allow for isolation of individual conformers, are alsoincluded. As an example, certain compounds of the invention may exist asmixtures of atropisomers or purified or enriched for the presence of oneatropisomer. Non-limiting examples of compounds which exist asatropisomers include the following compounds:

and

In some embodiments, the compound of structure (I) is a mixture ofatropisomers. In other embodiments, the compound of structure (I) is asubstantially purified atropisomer. In some embodiments, the compound ofstructure (I) is a substantially purified R-atropisomer. In some otherembodiments, the compound of structure (I) is a substantially purifiedS-atropisomer.

A “stereoisomer” refers to a compound made up of the same atoms bondedby the same bonds but having different three-dimensional structures,which are not interchangeable. The present invention contemplatesvarious stereoisomers and mixtures thereof and includes “enantiomers”,which refers to two stereoisomers whose molecules are non-superimposablemirror images of one another.

A “tautomer” refers to a proton shift from one atom of a molecule toanother atom of the same molecule. Embodiments thus include tautomers ofthe disclosed compounds.

The chemical naming protocol and structure diagrams used herein are amodified form of the I.U.P.A.C. nomenclature system, using the ACD/NameVersion 9.07 software program and/or ChemDraw Ultra Version 11.0.1software naming program (CambridgeSoft). For complex chemical namesemployed herein, a substituent group is typically named before the groupto which it attaches. For example, cyclopropylethyl comprises an ethylbackbone with a cyclopropyl substituent. Except as described below, allbonds are identified in the chemical structure diagrams herein, exceptfor all bonds on some carbon atoms, which are assumed to be bonded tosufficient hydrogen atoms to complete the valency.

Compounds

In an aspect, the invention provides compounds which are capable ofselectively binding to and/or modulating a G12C mutant KRAS, HRAS orNRAS protein. The compounds may modulate the G12C mutant KRAS, HRAS orNRAS protein by reaction with an amino acid. While not wishing to bebound by theory, the present applicants believe that, in someembodiments, the compounds of the invention selectively react with theG12C mutant KRAS, HRAS or NRAS proteins by forming a covalent bond withthe cysteine at the 12 position of a G12C mutant KRAS, HRAS or NRASprotein. By binding to the Cysteine 12, the compounds of the inventionmay lock the switch II of the G12C mutant KRAS, HRAS or NRAS into aninactive stage. This inactive stage may be distinct from those observedfor GTP and GDP bound KRAS, HRAS or NRAS. Some compounds of theinvention may also be able to perturb the switch I conformation. Somecompounds of the invention may favor the binding of the bound KRAS, HRASor NRAS to GDP rather than GTP and therefore sequester the KRAS, HRAS orNRAS into an inactive KRAS, HRAS or NRAS GDP state. Because effectorbinding to KRAS, HRAS or NRAS is highly sensitive to the conformation ofswitch I and II, the irreversible binding of these compounds may disruptKRAS, HRAS or NRAS downstream signaling.

Example 1 Biochemical Assay of the Compounds

Test compounds were prepared as 10 mM stock solutions in DMSO (Fishercat# BP-231-100). KRAS G12C 1-169, his-tagged protein, GDP-loaded isdiluted to 2 µM or 0.5 µM in buffer (20 mM Hepes, 150 mM NaCl, 1 mMMgCl₂). Compounds were tested for activity as follows:

Compounds were diluted to 50× final test concentration in DMSO in96-well storage plates. Compound stock solutions were vortexed beforeuse and observed carefully for any sign of precipitation. Dilutions areas follow:

-   For 100 µM final compound concentration, compounds were diluted to    5000 µM (5 µL 10 mM compound stock + 5 µL DMSO and mixed well by    pipetting.-   For 30 µM final compound concentration, compounds were diluted to    1500 µM (3 µL 10 mM compound stock + 17 µL DMSO) and mixed well by    pipetting.-   For 10 µM final compound concentration, compounds were diluted to    500 µM (2 µL 10 mM compound stock + 38 µL DMSO) and mixed well by    pipetting.-   49 µL of the stock protein solution was added to each well of a    96-well PCR plate (Fisher cat# 1423027). 1 µL of the diluted 50×    compounds were added to appropriate wells in the PCR plate using    12-channel pipettor. Reactions were mixed carefully and thoroughly    by pipetting up/down with a 200 µL multi-channel pipettor. The plate    was sealed well with aluminum plate seal, and stored in drawer at    room temperature for 10 minutes, 30 minutes, 2 hours or 24 hours. 5    µL of 2% formic acid (Fisher cat# A117) in de-ionized H₂O was then    added to each well followed by mixing with a pipette. The plate was    then resealed with aluminum seal and stored on dry ice until    analyzed as described below.

The above described assays were analyzed by mass spectrometry accordingto one of the following two procedures:

RapidFire/TOF Assay

The MS instrument was set to positive polarity, 2 GHz resolution, andlow mass (1700) mode and allowed to equilibrate for 30 minutes. Theinstrument was then calibrated, switched to acquisition mode and theappropriate method loaded.

After another 30 minute equilibration time, a blank batch (i.e., buffer)was run to ensure equipment is operating properly. The samples werethawed at 37° C. for 10 minutes, briefly centrifuged, and transfer tothe bench top. Wells A1 and H12 were spiked with 1 µL 500 µM internalstandard peptide, and the plates centrifuged at 2000 × g for 5 minutes.The method was then run and masses of each individual well recorded.

The masses (for which integration data is desired) for each well werepasted into the platemap and exported from the analysis. Masses for theinternal standards were exported as well. The data at 50 ppm wasextracted for the +19 charge state, and identity of well A1 was assignedusing the internal standard spike and integrated. Peak data was exportedas a TOF list and the above steps were repeated individually, for the+20, 21, 22, 23, 24, and 25 charge states.

Q-Exactive Assay

The masses and peak intensities of KRAS G12C protein species weremeasured using a Dionex RSLCnano system (Thermo Scientific) connected toa Q Exactive Plus mass spectrometer (Thermo Scientific).

20 mL of sample was each loaded onto a Aeris™ 3.6 µm WIDEPORE C4 200 Å,LC Column 50 × 2.1 mm column maintained at 40° C. at a flow rate of 600^(µL)/min with 20% Solvent A (0.1% formic acid in H₂O) and 80% Solvent B(0.1% formic acid in acetonitrile). The liquid chromatography conditionswere 20% solvent B for 1 minute, 20% to 60% solvent B for 1.5 minutes,60% to 90% solvent for 0.5 minute, 90% solvent B for 0.2 minute, 90% to20% solvent B for 0.2 minute, and then equilibrated for 1.6 minutesbefore the following sample injection. The flow rate was maintained at600 ^(µL)/_(min) throughout the sample analysis.

The mass spectrometer was operated in profile mode at a resolution of17500, 5 microscans, using 50 msec max injection time and an AGC targetof 1 × 10⁶, and a full mass range from 800-1850 m/z was recorded. TheHCD trapping gas was optimized for maximum sensitivity for intactproteins. The ionization method was electrospray ionization, which useda spray voltage of 4 kV, sheath gas flow set to 50 AU, auxiliary gasflow set to 10 AU and sweep gas flow set to 1 AU. The capillary iontransfer temperature was 320° C. and the S-lens RF level is set to 50voltage. Protein Deconvolution software (Thermo Scientific) was used forquantitative deconvolution of the charge envelopes of each proteinspecies in samples to determine the mass and intensity of each parentspecies (modified or unmodified protein). The modification percentageswere calculated based on deconvoluted peak intensities.

Other in vitro analyses are as follows:

Inhibition of Cell Growth

The ability of the subject compounds to inhibit RAS-mediated cell growthwas assessed and demonstrated as follows. Cells expressing a wildtype ora mutant RAS were plated in white, clear bottom 96 well plates at adensity of 5,000 cells per well. Cells were allowed to attach for about2 hours after plating before a compound disclosed herein is added. Aftercertain hours (e.g., 24 hours, 48 hours, or 72 hours of cell growth),cell proliferation was determined by measuring total ATP content usingthe Cell Titer Glo reagent (Promega) according to manufacturer’sinstructions. Proliferation EC₅₀ was determined by analyzing 8 pointcompound dose responses at half-log intervals decreasing from 100 µM.

Inhibition of RAS-mediated Signaling Transduction

The ability of the compounds disclosed herein in inhibiting RAS-mediatedsignaling was assessed and demonstrated as follows. Cells expressingwild type or a mutant RAS (such as G12C, G12V, or G12A) were treatedwith or without (control cells) a subject compound.
